If FET is true, many assumption of modern science would have to be edited or completely disregarded to fir that.
FET has a great many theories which accomplish this editing or disregarding.
However, I have seen no concrete proof or experimentation to validate these theories.
This is one of the reasons that I went on to develop a branch of FET that I call SF-FET, which contests that flight is possible even if the Earth where Flat and constantly moving upward.
So, I think that more alternate FET theories such as SF-FET should be developed and proposed.
Since no concrete proof has yet been provided for theories such as Bendy Light, the Universal Accelerator, or really any of the tenets, this leads me to believe that they cannot be the only way to rationalize a Flat Earth.
So in this thread, I invite everyone to propose subsets of FET.
Keeping with the tradition FET, these theories do not need to have any experimental validation. The only need to fit your observations, and only your observations.
Perhaps if more alternate theories such as SF-FET are developed, we can get closer to a true FET.
